VEHICLE-HUB.

SPECIFICATION forming part of Letters PatentNo. 298,014, datedMay 6, 1884-.

I Application filed September 6, 1882. Renewed October 9, 1883. (No model.)

To (1. whom it may concern:

Be it known that I, JOHN MONK, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Hubs for the Wheels of Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My .invention relates to improvements in the construction of hubs for the wheels of vehicles; and the object is to produce a hub that is very simple in construction, not liable to get out of order,economical in use,very strong and durable, and that can be produced at a very reasonable cost.

'The invention consists in providing the hubshell, made, preferably, of a single piece'of any suitable metal, with a series of radial ribs or fianges,-extending from the back bandof the hub to the front band thereof, so as to strengthen the outer shell, and permit it to.

be made of comparatively thin material with great strength. These ribs may be extended centrally,so as to enter slightly into the wooden core or center, to prevent it from turning circumferentially.

It also consists in the construction and arrangement of certain parts, as will be more fullydescribedhereinafter, referencebeing had to the accompanying drawings and the letters of reference marked thereon.

Like letters refer to like parts in the different figures of the drawings, in which- Figure 1 represents a side elevation of my improved hub. Fig. 2.is a longitudinal section of the same. Fig. 3 is a cross-section.

In the drawings, A represents a metallic hub-shell made so as to conform externally to the ordinary contour of a hub; and it can bemade plain or ornamental, as desired. In the central part of this shell are cast the mortises B, into which the ends of the tenons of the spokes are accurately fitted, and by the spaces .1), formed between the ribs 0 on each side of the tenons, the ends of the spokes will expand or swell sidewise, and will be thus securely held in position. On the inside of the shell are cast a series of radial ribs 0, as many as desired, and according to the size of hub and spokes, the sides of which ribs are beveled toward the outer side of the hub, as shown in Fig. 2, from the bottom or base of the same outward to the extent required. The lower ends of the tenons of said spokes bear against an annular groove, D, in the wooden core -E, shown in dotted line in Fig. 2,'and' in crosssection in Fig. 3, and havinga bearing at right angles to the bevel sides of the mortises B. The core E is firmly held in place by the shoulders a and the tenons of the spokes, which form a solid base, when driven in place and glued together. The ribs or flanges C may extend inward far enough to engagewith the wooden core about one-sixteenth of an inch, (more or less,) and thereby prevent itfrom turning circumferentially. The ribs extend" from the back band to the front band of the hub, and serve to greatly strengthen the shell hubs. No bolts or screws are required for securing the parts together; hence the hub is much stronger and will not be weakened, and all'the danger of splitting the hub, which heretofore has been a common occurrence, will be avoided. There will be no holes through which water can find its way to the inside of the hub, and thereby the rusting of the axle is prevented.

The hub can be very nicely finished orpainted in ornamental manner. The wooden core is also prevented from rotting, and will last much longer than ordinary hubs.

"I am aware that vehicle-hubs have been cast with a shell in one piece and united at the cendial tapering, ribs extending from the back band to the front band of the hub, in combination with a wooden core having a groove, into which the tcnons of the spokes enter and 5 form a solid base, substantially as described. 3. A hub having a shell made in one piece, and provided with radial ribs extending from the back band to the front band, and forming spaces 1), into which the spokes expand, as and I0 for the purpose set forth.

4. In a hub, the combination of a shell, A,

provided with radial tapering ribs 0, extending from the back band to the front band, in combination with a wooden core having radial groove D, in which the spokes are secured and I 5 form a solid base, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
